Split one column into multiple column

@Steven Henry Suhendra - Thanks for the question and using MS Q&A platform.

To split a single column into multiple columns based on certain conditions, you can use CASE statements to populate each column separately. Here’s an example based on your provided table.

Your goal is to separate the "Department" column into "Department" and "Special Department" columns. You can use SQL like this:

SELECT 
    No,
    Code,
    CASE 
        WHEN Code IN ('D001', 'D002') THEN Department 
        ELSE NULL 
    END AS Department,
    CASE 
        WHEN Code IN ('SD001', 'SD002') THEN Department 
        ELSE NULL 
    END AS Special_Department
FROM 
    db.table;

1. The first CASE statement checks if the Code is either 'D001' or 'D002' and assigns the value to the "Department" column. If the code doesn’t match, it returns NULL.
2. The second CASE statement checks if the Code is either 'SD001' or 'SD002' and assigns the value to the "Special_Department" column. If the code doesn’t match, it returns NULL.

This approach will give you the output you’re looking for, with "Department" values in one column and "Special Department" values in another.
